The low-temperature aerosol forming device mainly bakes atomized bombs at a low temperature of 200°C to 400°C to generate aerosol for users to inhale. It is convenient to use and healthier, and is favored by users.

目前，低温气溶胶形成装置的加热方式包括中心加热(通过安装在安装座上的发热体直接***雾化介质载体中而加热雾化介质载体)和四周加热(通过将雾化介质载体置于管式的发热体中而使其被加热)，其中，中心加热的发热体热效率高，因而也是主要的加热方式。然而，在实际使用过程中发现，气溶胶加热时会产生液体并流向靠近发热体底部的电极及安装座，产生电极的腐蚀及安装座的污染问题。At present, the heating methods of the low-temperature aerosol forming device include central heating (heating the atomized medium carrier by directly inserting the heating element installed on the mounting seat into the atomized medium carrier) and surrounding heating (by placing the atomized medium carrier in the tube The heating element of the type is heated), among which, the heating element heated by the center has high thermal efficiency, so it is also the main heating method. However, in the actual use process, it is found that when the aerosol is heated, liquid will be generated and flow to the electrode and the mounting seat near the bottom of the heating element, causing corrosion of the electrode and contamination of the mounting seat.

请一并参阅图3～图6，发热组件130位于第二壳体120内，作为气溶胶形成装置10的加热部件。具体地，发热组件130包括发热体131、安装座133和阻隔件135。安装座133用于固定发热体131，发热体131包括基体131a和发热线路，基体131a具有底面131b，发热线路位于基体131a上，发热线路包括发热部和与发热部电连接的发热电极131c，发热电极131c靠近底面131b安装座133与基体131a固定连接，安装座133与基体131a的连接处位于发热电极131c的靠近底面131b的一侧；至少一部分阻隔件135和安装座133与基体131a的连接处分别位于所述发热电极131c的两侧。Please refer to FIGS. 3 to 6 together. The heating element 130 is located in the second casing 120 and serves as a heating component of the aerosol forming device 10 . Specifically, the heating component 130 includes a heating body 131 , a mounting base 133 and a barrier 135 . The mounting base 133 is used to fix the heating element 131. The heating element 131 includes a base body 131a and a heating circuit. The base body 131a has a bottom surface 131b. The heating line is located on the base body 131a. The electrode 131c is fixedly connected to the base 131a near the bottom surface 131b, and the connection between the base 133 and the base 131a is located on the side of the heating electrode 131c close to the bottom 131b; at least a part of the barrier 135 and the connection between the base 133 and the base 131a respectively located on both sides of the heating electrode 131c.

上述发热组件130包括发热体131、安装座133和阻隔件135，阻隔件135用于吸收沿发热体131的表面流下的由于发热体131加热雾化介质载体而产生的可以流动的物质，使得安装座133及安装座133内的其他部件不容易受这些可以流动的物质的影响(例如腐蚀、短路等)，与传统发热组件130的卡持在安装座133与发热体131之间、起阻挡从发热体131表面流下的物质流入安装座133的密封件不同，上述发热组件130的阻隔件135能够吸收从发热体131流下的物质且不参与安装座133与发热体131的固定，这使得安装座133与发热体131之间的固定与阻隔件135无关且从发热体131流下的物质也更不容易腐蚀安装座133及其内部部件，使得安装座133的寿命更长，并且上述发热组件130在组装时操作也更简易。另 外，通过将安装座133与发热体131的固定位置设置在发热电极131c的靠近基体131a的底面131b的一侧，使得的安装座133与发热体131的固定位置不容易受高温的影响而老化，发热体131与安装座133之间的固定关系能维持更长的时间。所以，上述发热组件130可能改善气溶胶生成装置的电极腐蚀问题和安装座133污染问题，提高气溶胶形成装置10的使用寿命和组装效率。Above-mentioned heating assembly 130 comprises heating body 131, mounting seat 133 and barrier 135, and barrier 135 is used for absorbing the flowable substance that flows down along the surface of heating body 131 because heating body 131 heats atomization medium carrier, makes installation Other components in the seat 133 and the mounting seat 133 are not easily affected by these flowable substances (such as corrosion, short circuit, etc.), and are clamped between the mounting seat 133 and the heating element 131 of the traditional heating element 130 to block from The material flowing down from the surface of the heating element 131 flows into the seal of the mounting seat 133. The barrier 135 of the heating element 130 can absorb the material flowing down from the heating element 131 and does not participate in the fixing of the mounting seat 133 and the heating element 131. This makes the mounting seat The fixing between 133 and the heating element 131 has nothing to do with the barrier 135 and the material flowing down from the heating element 131 is also less likely to corrode the mounting seat 133 and its internal components, so that the life of the mounting seat 133 is longer. It is also easier to operate during assembly. In addition, by setting the fixing position of the mounting seat 133 and the heating element 131 on the side of the heating electrode 131c close to the bottom surface 131b of the substrate 131a, the fixing position of the mounting seat 133 and the heating element 131 is not easily affected by high temperature and aging. , the fixed relationship between the heating element 131 and the mounting base 133 can be maintained for a longer period of time. Therefore, the heating component 130 may improve the electrode corrosion problem of the aerosol generating device and the pollution problem of the mounting seat 133 , and improve the service life and assembly efficiency of the aerosol generating device 10 .

That is to say, the connection between the mounting base 133 and the base 131a is located below the welding point between the heating electrode 131c and the heating electrode lead 132 ; the welding area does not contact the inner wall of the mounting base 133 . The setting that the welding area is not in contact with the inner wall of the mounting base 133 can make the connection stability between the heating electrode 131c and the heating electrode lead 132 not easily affected by the shaking of the mounting base 133 . Certainly, in some embodiments, the welding area may also be in contact with the inner wall of the mounting base 133 , but the contact position between the welding area and the inner wall of the mounting base 133 is not the position where the mounting base 133 and the heating element 131 are fixed.

Optionally, the connecting flange 134 is integrally formed with the base body 131a.

支撑体133b为中空结构，位于盖体133a的远离底面131b的一侧并与盖体133a固定连接，发热体131穿过支撑体133b并向远离盖体133a的方向延伸，支撑体133b与发热体131非固定连接。也即是说，发热体131穿过支撑体133b，支撑体133b与发热体131之间有间隔或有接触但非固定连接。通过支撑体133b不与发热体131非固定连接的设置可以提高安装座133的寿命，延缓安装座133由于高温老化。支撑体133b与盖体133a围拢形成容纳腔，发热电极131c位于容纳腔内，连接法兰134完全收容在容纳内。可选地，发热电极131c的一部分位于容纳腔内，另一部分延伸到容纳腔外。进一步地，焊接区位于容纳腔内。在图示的实施例中，支撑体133b与盖体133a螺接，支撑体133b与发热体131之间有间隙。具体地，支撑体133b上具有螺纹孔，螺母穿过盖体133a与支撑体133b上的螺纹孔中的螺纹螺接。可以理解的是，在其他实施例中，支撑体133b与盖体133a还可以采用其他固定连接方式固定连接。The support body 133b is a hollow structure, located on the side of the cover body 133a away from the bottom surface 131b and fixedly connected with the cover body 133a, the heating element 131 passes through the support body 133b and extends away from the cover body 133a, the support body 133b and the heating element 131 Non-fixed connections. That is to say, the heating element 131 passes through the supporting body 133b, and the supporting body 133b and the heating element 131 are spaced or contacted but not fixedly connected. The setting that the supporting body 133b is not fixedly connected with the heating element 131 can improve the service life of the mounting seat 133 and delay the aging of the mounting seat 133 due to high temperature. The supporting body 133b and the cover body 133a surround to form a housing cavity, the heating electrode 131c is located in the housing cavity, and the connecting flange 134 is fully accommodated in the housing.

It can be understood that, in other embodiments, the support body 133b and the cover body 133a may also be fixedly connected by other fixed connection methods.

加热待加热物体20后会产生可以流动的物质(例如雾化介质载体加热后会形成可以流动的污垢，下文简称为污垢)，由于发热体131与第一壳体110之间有不可避免的间隔，因而这些可以流动的物质会沿着发热体131的表面向安装座133方向流动，进而流向安装座133下方的其他部件。阻隔件135则用于吸收这些可以流动的物质，以避免其向安装座133的方向流动。After heating the object 20 to be heated, there will be flowable substances (for example, after the atomization medium carrier is heated, flowable dirt will be formed, hereinafter referred to as dirt), because there is an inevitable gap between the heating element 131 and the first housing 110 , so these flowable substances will flow along the surface of the heating element 131 toward the installation seat 133 , and then flow to other components below the installation seat 133 . The barrier 135 is used to absorb these flowable substances, so as to prevent them from flowing toward the mounting seat 133 .

具体地，阻隔件135靠近发热体131和安装座133；阻隔件135与安装座133和发热体131中的至少一个是非固定连接。通过阻隔件135与安装座133和发热体131中的至少一个为非固定连接，可以使得上述发热组件130的组装更加简易，不必将阻隔件135作为将发热体131固定到安装座133上的中间必备元件，发热体131与安装座133之间的固定与阻隔件135无关。并且，在一定程度上也避免了阻隔件135作为将加热待加热物体20产生的可流动物质的导入安装座133的导流件，或者也能避免阻隔件135在受到安装座133和发热体131相抵持的力而无法发挥其吸收可流动物质的作用。Specifically, the blocking member 135 is close to the heating element 131 and the mounting seat 133 ; the blocking member 135 is not fixedly connected to at least one of the mounting seat 133 and the heating element 131 . Through the non-fixed connection between the barrier member 135 and at least one of the mounting base 133 and the heating element 131, the assembly of the above-mentioned heating element 130 can be made easier, and it is not necessary to use the barrier member 135 as a middle for fixing the heating element 131 to the mounting base 133. As an essential element, the fixing between the heating element 131 and the mounting seat 133 has nothing to do with the barrier 135 . Moreover, to a certain extent, the barrier member 135 is also avoided as a flow guide for introducing the flowable substance produced by heating the object 20 to be heated into the installation seat 133, or the barrier member 135 can also be avoided when being subjected to the installation seat 133 and the heating element 131. The opposing force cannot play its role in absorbing flowable substances.

Optionally, the entire barrier 135 is located outside the mounting base 133, and the connection between the entire barrier 135 and the mounting base 133 and the base body 131a is respectively located on both sides of the heating electrode 131c. Farther away from the bottom surface 131b, the barrier 135 is not fixedly connected to the heating element 131, the barrier 135 is not fixedly connected to the mounting base 133, or the barrier 135 is not fixedly connected to the heating element 131 and the mounting base 133. It can be understood that, in other embodiments, the blocking member 135 may also be entirely located in the mounting seat 133 or a part of the blocking member 135 is located in the mounting seat 133.
